Actress Amanda Bynes has returned to Twitter.com to thank her fans for their continued support as she works on overcoming her mental health issues.

The Hairspray actress was admitted to hospital last August (13) on an involuntary psychiatric hold following months of bizarre behaviour, and she completed a stay in rehab in December (13).

Her parents became her temporary conservators and Bynes has returned to their home in California as she tries to bounce back to full health.

The star, who has also enrolled on a course at the Fashion Institute of Design and Merchandising in Orange County, has now reached out to her three million followers on Twitter after months of silence.

She writes, "Hi everyone! I'm busy studying at Fidm but I want to say I love you to my fans!"
